Question

what is the missing term in the arithmetic sequence 6, __,30

Answer 1

this being an arithmetic sequence, we need to find what is called arithmetic mean ..

Do you know what that is ?

Answer 2

No not really aha im not really good with math but I think its 18
its multiple choice

Answer 3

12, 18, 22, 15

Answer 4

lets solve this problem

let the sequence be a,a+d,a+2d where a is the first term and d is the common difference

does this make sense ?

Answer 5

umm no lol i'm so sorry do you mean like 6+30 and 6+2(30)?

Answer 6

in arithmetic sequence, the difference between next term and current term is same

let your middle term be x

so
x-6 = 30-x
get x from here

Answer 7

1,3,5,7,9,...
here each term comes when add a fixed number except first one
means
a1 =1
a2= 1+2 =3 (second term)
a3= 3+2 =5

Answer 8

so it would be 18 I did what you said @hartnn and I got 18

Answer 9

I mean the sequence be a, a+d, a+2d... which means

a= 6
a+2d= 30

using this you can find d...
what you need is a+d :)

Can you solve it from here ?
